The list contains all known $abc$-triples quality at least $1.4$, as givin in
[2]. An $abc$-triple is a solution of the equation $a+b=c$ with coprime integers $0 < a \leq b < c$. The quality of an $abc$-triple is defined as $q = \log(c)/\log\text{rad}(abc)$, where $\text{rad}(abc)$ is the radical of $abc$, that is, the product over all prime divisors of $abc$.
